Verbal Irony
When the characters say one thing but mean something else “The morning sun comes right in the window, Mr. Perkins….” Does the Landlady intend for Billy to actually see the morning sunshine? Why does the Landlady continue to forget Billy’s name?
6. Situational Irony
The situation turns out to be just the opposite of what we’d expect He has never been to Bath before. He seems to be afraid of boardinghouses but thinks this house is pleasant. It is ironic that a seemingly sweet, nice Landlady will more than likely poison Billy just as Mulholland and Temple.
